Dental patient chairs are a necessary purchase in a dental office. Choosing a chair that is comfortable for both the patient and dentist is important. Some features of dental chairs can include: thin backrest, swivel, ergonomic, soft cushioning, programmable positions, double-articulating headrest, magnetic headrest, movable armrest for easy patient entry/exit, seat tilt and footswitch or touchpad. Certain features of dental patient chairs may be more important than others, for example, having a thin backrest allows the dentist adequate leg room for better access to the dental cavity. Another aspect to consider is whether or not the chairs upholstery is replaceable; having to replace a dental chair because the upholstery is worn out is not economical. The ability to only purchase the upholstery can greatly extend the life of a dental patient chair. Most dental chairs employ a hydraulics system for powerful and continuous movement of the chair. It is also a good idea to research which options/modules are compatible with the dental chair before purchase. Be sure that whichever vendor is chosen that the dental chair purchased has a warranty and reliable customer support.
